The integration of bioinspired chiral cellulose nanocrystal (CNC) films into transistor devices with distinct sensing properties for left‐ and right‐handed circular polarized light (LCPL and RCPL, respectively) is reported. The CNC films with a left‐handed internal long‐range order are infiltrated with sodium ions to yield solid‐state electrolytes with photonic properties capable of LCPL reflection and RCPL transmission. They are employed as gate dielectrics in sputtered amorphous indium–gallium–zinc oxide (a‐IGZO) transistors. The obtained devices operate in depletion mode at low voltages (<2 V) with On–Off ratios of up to 7 orders of magnitude, subthreshold swings around 80 mV dec⁻¹, and saturation mobilities up to 9 cm² V⁻¹ s⁻¹. Combining the photonic character of the CNC films with the light sensitivity of a‐IGZO, the devices are capable of discrimination between LCPL and RCPL signals in the blue region. These type of devices can find application in photonics, emission, conversion, or sensing with CPL but also imaging or spintronics.

用于圆偏振光传感的光子纤维素纳米晶体固体电解质上的场效应晶体管

据报道，具有生物启发性的手性纤维素纳米晶体（CNC）膜已集成到晶体管器件中，该器件对左手和右手圆偏振光（分别为LCPL和RCPL）具有不同的传感特性。左手内部长程有序的CNC膜被钠离子渗透，产生具有光子特性且能够进行LCPL反射和RCPL传输的固态电解质。它们被用作溅射的非晶铟-镓-氧化锌（a-IGZO）晶体管的栅极电介质。将所得到的器件在耗尽模式在低电压下操作（<2 V）与通断约80毫伏癸多达7个数量级，亚阈值摆幅的比例^-1，和饱和迁移率高达9厘米² V ^-1小号^{- 1个}。结合CNC薄膜的光子特性和a-IGZO的光敏度，该器件能够区分蓝色区域中的LCPL和RCPL信号。这些类型的设备不仅可以用于光子学，发射，转换或CPL传感，还可以应用于成像或自旋电子学。
